Describes how to convert uM-FPU 3.1 code to uM-FPU64. Provides overview of different features, instruction changes, new and modified instructions, and converting 32-bit calcualtions to 64-bit calculations.

Describes how to use the uM-FPU V3.1 chip to drive a serial graphic display.
It offloads all of the graphics overhead from the microcontroller, so that virtually any microcontroller can display complex graphs on a serial graphic displays.

Describes how to calculate sunrise and sunset times. A set of uM-FPU V3.1 user-defined functions are provided to implement the calculations and read date, time and position information from a GPS receiver.
